I think a M&P Compact would be a good choice. In fact, several weeks ago I bought a S&W M&P40c. I can't say much about it yet as it hasn't seen much range time, but they seem to be good guns, and it fits my hand very well. Seems about a perfect blend of capacity and size for a concealment gun. As for the price, I'd think it would be hard to find one used for much less in good condition. However, with current prices on a new one, I'm not sure it makes sense to buy one used right now. You can find a new one online for between $400-450, and depending upon your local gun prices, it might not be much more in person. Then, depending upon your state, you can get some free ammo and extra mags (and a mag loader) or $75 off.
